Solving Problems: Using Ohm's law

1 answer:

8 0

A) Since V = I/R, we know that VR = I so 16 x 24 = 384.

B) I/V = R so 2/6 which = 0.333

and for C i physically cannot open the pic but good luck and use Voltage = Current / Resistence

The Moon takes about 27 days to orbit the Earth. Assuming a circular orbit, how fast is it orbiting? Express your answer in km/h

Vinvika [58]

Answer:

3727.24km/h

Explanation:

Hello!

To solve this problem we must first know what is the distance from the earth to the moon, this will be our radius.

=384400Km

Then we find the distance traveled which would be the perimeter of a circle = 2πr, finally to find the speed we divide the distance traveled by 27 days.

Finally we use conversion factor to have the speed in km / h

solving

$perimeter= 2(3.14)r=2(3.14)(384400Km)=2415256.432km\\Speed=\frac{2415256.432km}{27days} *\frac{1day}{24h} =3727.24km/h$

the moon is orbiting at speed of 3727.24km/h

What happens to the average kinetic energy of water molecules as water freezes? It decreases as the water absorbs energy from it

Morgarella [4.7K]

Answer:the average kinetic energy is directly proportional to the temperature . When water freezes, the temperature decreases and therefore, the average kinetic energy will also decreases as well.
